IMPRVEMENT IN SEDIMENT-CHAMBER IEOR LAMP-POSTS.

The Schedule referred to in these Letters Patent and making part of the same.'

I, Gnonen C. Bovnv, of Cincinnati,A Hamilton county, Ohio, haveinvented a. new and useful Sedinent- Nature and Objects of the Invention. i

My invention relates to a device for relieving street gas-lights from a class of defects to which they are at present liable, owing to the stoppage ot theservice and supply-pipes by the moisture which condenses on their inner surface, and often collectsin the elbow or quarter-turn, at the foot of the pipe, in sutcient quantity to seal up the pipe, and prevent the passage ot' gas. This impediment is further increased by the rust which scales off from the interior of the pipe, and falls tothe same point, and'by the freezing of said moisture incident to unusual depressions of temperature; and i My invention consists in applying, at the foot of the post, areservoir or sediment-chamber, of suiicient capacity to receive and hold such deposit for a very long time, without its accumulation in any way interfering with the supply of gas to the burner.

General Description 'with Reference to the Drawings.

Figure l is a vertical section, partlyin elevation,ot` a lamp-post, provided with my sediment-chamber.

Figure 2 is a horizontal section of the same, taken on the line x x.

Fi gnre 3 is a perspective view of my sedimentchamber, detachedfrom the post.

Figure 4 is a perspective view, showing a chamber at its lower end for the insertion of the service-pipe E, which leads from the strcetmain F to the post, entering the box D, near its upper end.

Said pipe E is screw-threaded at both ends, each in a reverse directionto the other, thus enabling it to be secured to both main and box by one operation.

` In applying my sediment-chamber to 1amp-posts already in use, a box, of the described shape, is inserted through the slot in the post, and supported upon any suitable foundation, to prevent it from settling under the weight of the pipe; but, in setting up new posts, a box ot' the cylindrical form, shown in tig'. A4, may be first placed in the ground, and the post set over it, thus securing a much greater capacity of chamber.

Itis evident that no deposit from the pipes will interfere with the supply of gas until the `chamber is nearly full, which would not take place in a very long time, it' at all, during the period of duration ot' the service-pipe and post.

Another benefit, incident to this invention, grows out of the fact that the box D forms au`equalizingchamber, which tends, by its capacity, to maintain an equal pressure of gas, and thus insure a steady flame. It will be seen that` my improvement can be easily appliedrto existing lamp-posts, which are not necessa;

.rlyair-tight, as would be the case were the post'itselt' used for the reservoirfand should any part of therapparatus become defective, it can be easily and cheaph renewed, without disturbing the lainpfpo'st.

Claim.

I claim as my invention- The sediment-chamber D, constructed separately from the lamp-post, to he used in combination with such post, and with the service-pipe E, and gas-pipe B, substantially as above described.
